  1. Abstract : variations of flow pattern, flow velocity in deep poo l and side bar, mainstream thread, and water surface, caused by excavation project, are investigated by two - dimensional mathematical model in an orthogonal curvili near coordinate system. the change of bed - load transport rate, and redeposition r ate are predicted. the influences of the excavation project on navigation are ana lyzed. grid - type and flat - type excavation alternatives are proposed and discuss ed

  2. Furthermore, the spectrum characteristics of normal seawater and oil polluted water are also analyzed and discussed, from which we reach the conclusions that the transformation method can be used for obtaining reflectance data and airborne hyperspectral data can be used for oil film detection as well

    進一步對正常海水和油污染水體的光譜特性進行分析，通過反射率曲線比較，得出運用基於圖像特徵的反射率處理模型提取光譜信息和運用航空高光譜數據進行海上油污染檢測的可行性。
  3. In this paper, an approach of the systematic artificial neutral net was introduced into the analysis on the ship - against - bridges probability with a computer programs. based on the basic data of the present 12 typical bridges as the sample, 4 chief influential factors as the input coefficient, such as the bridge span, the water flow rate, the incline angle between water flow direction and the direction normal to bridge axis, and the curve in the course near the bridge area, with the ship - against - bridge probability as the output coefficient, the intelligent judging system of the ship - against - bridges probability reflecting the influence of the above input parameters is obtained after training

    本文首次將人工神經網路系統方法引入了船撞橋概率的研究當中，編制了計算程序，成功地以現有12座典型橋梁的基礎數據為樣本，以橋梁跨徑、水流流速、水流方向與橋軸法線的夾角以及橋區航道彎曲度等4個船撞橋主要影響因素為輸入參數，以船撞橋概率為輸出參數，經訓練得到了能較好地反映上述輸入參數影響的船撞橋概率判斷系統。
